FLYING-MACHINE.

Specification of Letters Patent. P t ted Oct. 27, 1914.

Application filed September 9, 1913. Serial No. 788,944.

To all whom it may concern Be it known that I, HENRY DENNIs, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Flying-Machines, ofwhich the following is a specification, reference being had therein to the. accompanying drawing.

This invention relates to flying machines, and the principal object of the invention is to provide a machine having an improved wing construction which is so constructed that the upperand lower wings willbe simultaneously raised and, lowered, and also to provide pivotally mounted planes in the wings which are operated simultaneously with the vertical movement of the wings to permit an. air current to pass through the wings whenthe wings travel upwardly, but

to prevent the air. current from passing through the wings when the wings travel downwardly.

Another object of the invention is to provide an improved means for moving the upper wings and for causingthe lower wings to move with the upper wings.

Another object of the invention is to provide an improved means for rocking the pivotally mounted planes when the wings are moving.

Another-object. of the invention isto provide an improved. type of frame for the flying machine.

With these and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

y In the accompanying drawings :Figure 1 is a front elevation of the flying machine. Fig. 2 is a side elevation of the machine. Fig. 3 is a top plan view of the machine with the canopy removed. Fig. i is a vertical longitudinal sectional View through the machine. Fig. 5 is a vertical transverse sectional view through the machine along.

the line 55, in Fig. 2. Fig. 6 is a fragmentary sectional view showing the manner of pivotally connecting the planes with the wings. Fig. 7 isa fragmentary sectional view of the bearing showing the manner of connecting the drive shaft with the rod operating the wings. Fig. 8 is a perspective view of the block which is mounted upon the shaft which operates the wings.

Referring to the accompanying drawings it will be seen that this invention comprises a platform 10 which is supported .by the wheels 11. and which carries the standards 12 which support the upper platform 13 provided with the railing 14:. This platform wings 17 are substantially straight throughout their length and terminate in downwardly extending tapered end portions 21 which permit the wings to be raised easily and to cause them to take a better grip upon the atmosphere when pushed downwardly. The upper Wings 22 which are curved throughout their length are pivotally connected near their inner ends with the arms 23 at the upper ends of the standards :24

mounted adjacent the forward and rear ends of the platform 13. These upper wings 23 are also provided with transversely extending planes 25 pivotally mounted by means of the pins 26 similar to the planes 19. It

should be noted that since the upper wings are curved as clearly shown in Figs.-1 and that theupper wings will obtain a very firm grip upon the atmosphere, thus permitting the machine to be quickly lifted from the ground when the wings are operated by; the mechanism to be hereinafter described. A canopy 27 extends longitudi nally above the center of the frame and is supported by the standards 28 having their lower ends: connected with the blocks. 29 secured to the standards 24 i Blocks 30 are slidably mounted in the standards 24:.and are connected by the shaft 31 which passes through the slots 32 formed in the inner end portions of the upperwings M 4 22. It will thus be seen that when the blocks 30 are moved vertically that the wings 22 will be rocked upon their pivots 33 and, thus cause the machine to be raised from the ground. Rods 34L connect the wings 22 with the lower wings 17 audit will thus be evident that when the upper wings are moved that the lower wings will be simultaneously moved in the same direction although as indicated by the dotted lines in Fig. 5 these wings 17 will move in a difi'erent are from the wings 22. Rods 35 are pivotally connected with the rail 14 at their inner ends and with the inner edge portions of the planes 25 at their outer ends. Links 36 are connected with the rods in termediate the length of the rods and have their lower ends connected with the inner edge portions of the planes 19 as clearly shown in Fig. 5. From an inspection of this figure it will be seen that when the wings are raised to the position indicated in dotted lines that the planes will be tilted to the positions indicated, thus permitting the air to pass throu h the wings and thus pre vent the upwar. movement of the wings from causing the machine to have a tendency to move downwardly through the air. A crank shaft 37 is rotatably mounted in the lower portions of the standards 24.- and is supported intermediate its length by the bearings 38. Links 39 connect the crank shaft with the pins 40 passing through the lower portions of the blocks 30 and it will, therefore, be seen that when the crank shaft is rotated by the sprocket chains 41 which pass around the sprocket wheels 42 and around the sprocket wheels 4:3 mounted on the shafts of the motors 44 that the blocks 30 will be reciprocated vertically and through the standards 24: and thus the wings caused to move as already described. The propeller 45 is mounted upon the shaft 4-6 and: carries a gear 47 meshing with a gear 48 mounted upon one end of the shaft crank shaft 37. This propeller will, therefore, be

rotated when the engines a l are started and will drive the machine forwardly.

The usual rear rudder 19 and forward rudder 50 are provided together with suitable controlling means such as a handle 51 for the rear rudder and the bell crank lever 52 and link for the forward rudder.

A switch box 54 is provided for controlling the motors 44- and battery boxes 55 are provided for holding the batteries which supply the current to the motors 44.

When operating this machine the motors are started by moving the lever 56 on the switch box and the wings and propeller blade will be caused to move through the mechanism described. These wings have a flappmgmotion somewhat similar to that of the wings of a bird and it will, therefore, be possible to raise the machine in a comparatively small open space. The machine may be guided while in the air by the ru dders and when it is desired to return to the earth the lever 56 may be moved to de crease the speed of the motors and the malower wings, rods connecting said upper wings with said lower wings for causing said lower wings to be moved simultaneously with said upper wings, and means for rocking said upper Wings. 1

2. A flying machine comprising a frame having upper wings, lower wings, pivotally mounted upper wings, planes pivotally mounted in. said wings, rods connecting the planes of said upper wings with said frame, links connecting the rods with the planes of said lower wings, rods connecting said upper and lower wings, and operating means for moving said upper wings.

' 3. A flying machine comprising a frame, upper wings pivotally secured to said frame, lower wings pivotally secured to said frame, means secured to said wings for swinging the same simultaneously, plane's carried by said wings, and means extending from saidframe and engaging said planes whereby said planes will be automatically swung as said wings are moved.

4. A flying machine comprising a frame,

- upper wings pivot'ally secured to said frame,

lower wings pivotally secured to said frame,

a rod connecting said wings together, means for moving said upper wings wliereby said lower wings will be moved simultaneously, planes carried by said wings, a rod extending from each side of said frame and engaging the plane of each upper wing, linksconnected to the central portions of said rods and engaging the rear portions of the planes of the lower wings whereby when said wings are shifted said rods and links will automatically shift said planes for allowingt'he passage of air currents therethrough or will swing said planes to a closed position as the wings move downwardly.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.
